This video, released by the Ellen MacArthur Foundation, suggests that a way to evoke systemic change is to rethink the economy as circular, rather than linear.

The basis for this thinking is that the linear way in which the world economy currently operates fuels a culture of consumption and creates more waste than is sustainable in the long term. In contrast, the living world operates in a circular cycle where the waste of one species provides the food for another and resources flow.

What would a circular economy look like in practice? The video suggests that it's about redesigning and rethinking products so that after they have been used by humans, their component parts return to manufacturers, with biological elements being used to support agriculture and valuable resource parts such as metals being used in the creation of new products. In this way, today's goods become tomorrow's resources, forming a circular cycle.

So what do you think? Could the circular economy present a vision of a prosperous and sustainable future? Are companies ready to really rethink the way they operate and turn traditional business models on their head? What will be the catalyst for the systemic change that is needed for this model to become a reality?
